Bharat Sanchar Nigam [BSNL] — tunefind

Please deactivate the present caller tune. It is a english song which i have never asked for. I don't know how the caller tune is changed without my knowledge. Ok deactivate it immediately i don't know if there is any amt charged for changing the caller tune by the bsnl by themselves. We select some tune which we like and use it
But how it will be changed without our knowledge. English caller tune is not good want to be changed immediately. Thanking in advance.
